Abstract

The invention discloses a cross-language retrieval method oriented to big data. The cross-language retrieval method oriented to the big data comprises the following steps: constructing a bilingual word vector model by use of cross-language relationship between Chinese-English Wikipedia entries; translating query by use of the bilingual word vector model; finally, constructing a new query execution retrieval according to a candidate translation. The bilingual vector model utilizes source language query vectors as input, and the similarity degree of target language documents similar to query vector semantics is output; during a query translation process, a canonical correlation analysis result is adopted. Through starting from the angle of automatic query translation and utilizing the document semantic similarity characteristic of different languages, a shared semantic space of two languages is found, and semantic translation on query is performed in the shared space, so that an automatic query translation function is realized.

Description

technical field [0001] The invention belongs to the technical field of cross-language retrieval, and in particular relates to a big data-oriented cross-language retrieval method. Background technique [0002] With the continuous development of information technology and the deepening of cultural exchanges around the world, the Internet has gradually become a global multilingual information sharing warehouse. How to quickly and accurately obtain user-satisfied cross-language information from the massive information database is an urgent problem to be solved in the multilingual information age. [0003] Cross-language information retrieval is an important means of obtaining multilingual information. Cross-language information retrieval (Cross-language information retrieval, CLIR) refers to a query constructed in a certain language to retrieve information expressed in one or more other languages. information retrieval techniques or methods. As a branch of the information retr...
